METHOD OF TREATING USED-BURLAP BAGS Filed 11314, 1930 Patented Aug. 4,1931 f i t GEORGE I. GOLDNYN, OF CHICAGO, ILLINOIS METHOD OF TREATINGUSED BUR-LAP BAGS Application filed April 14, 1930. Serial No. 443,940.

ti on aswell as others together with the many advantages thereof willmore fully appear as I proceed with my specification.

In the drawings Fig. 1 is a perspective view of a used burlap bag afterthe seam thereof has been treated in accordance with my invention.

Fig. 2 is a perspective View through the seam of a used burlap bag afterit has been turned inside out and has been treated in accordance withone step of my invention.

Fig. 3 is a view similar to Fig. 2 after the seam has been treated inaccordance with another step of my invention.

In that industry wherein used burlap bagsare reconditioned for reuse,one of the main difficulties met withis the treating of the seam. Suchbags when presented to the trade after cleaning and renovating, areturned inside out to obliterate the usual brands and trade marks printedupon the bags. VJhen thus turned inside out the folded over and stitchedtogether margins of the bag fabric from which the seam is made areexposed and the edges thereof are always more or less'frayed and raveledand present an undesirable appearance.

Again with these margins on the outside of the turned bag, the frayededges slough off in use and soon approach the original stitching holdingthem together with the result that the seam as a whole weakens and opensup so that the bag soon becomes unfit for further service.

In the original making of a burlap bag 1, a piece of burlap of thedesired area is folded ver upon itself to its edges in i i the ts. .2and 3 of the bag each with a turned over margin 2 am. 8 respectively anda line of stitching 4- is then run along one side and end of the folded.over bag material. Thereafter the thus far finished bag is turned insideout to provide a finished bag ready for the trade as a plain unprintedbag.

After the bag has been in use, and its contents have been removed, it isgenerally considcred as Waste by the original purchaser. To reconditionthe bag, for reuse certain establishments clean and mend the bags. Asthe bags cannot go back to the purchasing public with the originalbrands and trade marks on the outside, they are again turned inside out.This, however, leaves the frayed edges 2" and 3 of the margins 2* and 3of the bag, extending toward the opposite side of the bag and beyond thenow exposed line of stitching 4 so that the bag is indeed weakened anddoes not have the neat appearance which so appeals to the purchaser.

In accordance with my invention, I run a line of overcast stitching 5through said folded over margins and the bag wall portions engagedthereby. In running in this line of stitching, the interlooping portions5 thereof are spaced well within the frayed edges 2* and 3" and theloops 5" thereof pass around the folded edges of the seam and cross theoriginal line of stitching.

Thereafter by suitable mechanism, I trim off the frayed edges 2* and 3*adjacent but beyond the interiooped portions 5 of the overcast stitchingas shown in Fig. 3 and this leaves the bag with a clean cut appearingseam bound by the loops 5 of the overcast stitching and with theoriginal line of stitching 4 covered and protected thereby.

Thus the seam of the bag is made much stronger and has that appearancewhich readily enhances its salability.

While in describing my invention, I have referred in detail to thearrangement of the parts of the bag, as well as to the manner in whichthey are operated upon, the same is to be considered merely asillustrative so that I do not wish to be. limited thereto except as} mayi epenifimilly m re-wit; in t e filliilit'rldarl claim.

I claim as my invention e The method of treating used bags of burlap andthe likewhioh consists in turning the bag l inside out, thereby exposingmargin portions 5 above and below the body fabric layers of the bag, thefrayed edges of said margin portions extending inwardly and alsoexposing the line of stitching which passes through the two marginportions and the two body layers to p secure them together, in forming aline of overcast stitching with the interconnecting loops thereofpassingthrough both margin portions and both layers of the bag fabric ina plane between the first mentioned line of stitching and said frayededges and with the other loops of the overcast stitching passing 7around the folds of said margin and body fabrioand crossing the firstmentioned line i of stitching and, subsequent to turning the g baginside out, removing the frayed edges of the margins. y In testimonywhereof, I have hereunto set myhand, this 9th day of April, 1930.
